11.7 I can’t build Bison

I can’t build Bison because make complains that
msgfmt is not found.
What should I do?

Like most GNU packages with internationalization support, that feature
is turned on by default. If you have problems building in the po
subdirectory, it indicates that your system’s internationalization
support is lacking. You can re-configure Bison with
--disable-nls to turn off this support, or you can install GNU
gettext from ftp://ftp.gnu.org/gnu/gettext/ and re-configure
Bison. See the file ABOUT-NLS for more information.
